    <p>I've recently written a very similar application on a similar setup, so I do have several insights.</p> <p>The proper way of doing what you need is to have a pub-sub backend. There's only so much you can do with simple <code>ConnectionHandler</code>s. Eventually, handling class-level sets of connections starts to get ugly (not to mention buggy).</p> <p>Ideally, you'd want to use something like Redis, with async bindings to tornado (check out <a href="https://github.com/evilkost/brukva">brukva</a>). That way you don't have to mess with registering clients to specific channels - Redis has all that out of the box.</p> <p>Essentially, you have something like this:</p> <pre><code>class ConnectionHandler(SockJSConnection): def __init__(self, *args, **kwargs): super(ConnectionHandler, self).__init__(*args, **kwargs) self.client = brukva.Client() self.client.connect() self.client.subscribe('some_channel') def on_open(self, info): self.client.listen(self.on_chan_message) def on_message(self, msg): # this is a message broadcast from the client # handle it as necessary (this implementation ignores them) pass def on_chan_message(self, msg): # this is a message received from redis # send it to the client self.send(msg.body) def on_close(self): self.client.unsubscribe('text_stream') self.client.disconnect() </code></pre> <p>Note that I used <a href="https://github.com/MrJoes/sockjs-tornado">sockjs-tornado</a> which I found to be much more stable than socket.io.</p> <p>Anyway, once you have this sort of setup, sending messages from any other client (such as Django, in your case) is as easy as opening a Redis connection (<a href="https://github.com/andymccurdy/redis-py">redis-py</a> is a safe bet) and publishing a message:</p> <pre><code>import redis r = redis.Redis() r.publish('text_channel', 'oh hai!') </code></pre> <hr> <p>This answer turned out pretty long, so I went the extra mile and made a blog post out of it: <a href="http://blog.y3xz.com/blog/2012/06/08/a-modern-python-stack-for-a-real-time-web-application/">http://blog.y3xz.com/blog/2012/06/08/a-modern-python-stack-for-a-real-time-web-application/</a></p>

    1. CODude, you even read the question? This question: "Is there a tornado in the function which send message to all connected clients", but not about how to create backend for store connection objects.

    2. CO@Denis, i think Yuval Adam answered exactly what i wanted to know. I am not 100% sure yet, but please consider undoing your downvote.

    3. CO@Yuval Adam: Can you please explain why you found sockjs better than socket.io? I can still switch as i am not bound to a specific library

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
